Heterogeneous Removal of Water-Soluble Ruthenium Olefin Metathesis Catalyst from Aqueous Media Via Host-Guest Interaction10:39

Heterogeneous Removal of Water-Soluble Ruthenium Olefin Metathesis Catalyst from Aqueous Media Via Host-Guest Interaction

8.3K
A removable water-soluble N-heterocyclic carbene (NHC) ligand in aqueous media via host-guest interaction has been developed. We demonstrated representative olefin metathesis reactions in water as well as in dichloromethane. Via either host-guest interaction or extraction, the residual ruthenium (Ru) catalyst was as low as 0.14 ppm after the...

Photoluminescence: Fluorescence and Phosphorescence

3.6K
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

Variables Affecting Phosphorescence and Fluorescence

1.3K
Fluorescence and phosphorescence are essential phenomena in fields like analytical chemistry, biological imaging, and materials science, where they detect molecular properties and visualize cellular structures. Understanding the variables that influence these luminescent behaviors is crucial for maximizing accuracy and efficiency in their applications. These variables can broadly be grouped into chemical structure, solvent properties, and external conditions, each playing a distinct role in...

Fluorescence and Phosphorescence: Instrumentation

1.4K
Fluorometers and spectrofluorometers are two types of instruments used for measuring molecular fluorescence. These instruments differ in how they select excitation and emission wavelengths and the type of light sources they utilize. Fluorometers use absorption interference filters to choose excitation and emission wavelengths. The excitation source in a fluorometer is typically a low-pressure mercury vapor lamp that emits intense lines distributed throughout the ultraviolet and visible regions.

Area of Science:

  • Materials Science
  • Organic Chemistry
  • Photophysics

Background:

  • Previous reports indicated triarylboranes exhibit rapid, though transient (RTP), emission.
  • Purity of crystalline triarylboranes was found to be critical for RTP observation.

Purpose of the Study:

Main Methods:

  • Synthesis of binary host-guest systems using distinct triarylboranes.
  • Tuning of host/guest structures and doping concentrations.
  • Characterization of photophysical properties, including afterglow duration.
  • Computational analysis of triplet-triplet energy transfer rates.

Main Results:

  • Pure triarylboranes do not exhibit RTP; RTP is linked to impurities or specific matrix conditions.
  • Designed binary host-guest systems achieve visible afterglow up to 8 seconds at ppb doping levels.
  • Materials show high sensitivity to oxygen in non-annealed matrices.
  • Computational modeling correlates phosphorescence trends with energy transfer rates.

Conclusions:

  • Material purity is paramount for observing intrinsic RTP phenomena.
  • Host-guest engineering enables efficient organic RTP with ultra-long afterglow.
